Detecting attempts to defeat facial recognition

ABSTRACT

A device may select an individual that is a candidate for authentication by facial recognition. The device may identify a facial area of the individual and an area of exposed skin of the individual. The device may obtain a first temperature associated with the facial area of the individual and a second temperature associated with the area of exposed skin of the individual. The device may determine, based on the first temperature and the second temperature, whether an appearance of the facial area of the individual is likely altered by a face-altering technology. The device may selectively perform facial recognition on the facial area of the individual based on whether the appearance of the facial area of the individual is likely altered by the face-altering technology.

BACKGROUND

A facial recognition technique may identify an individual that is depicted in an image or a video frame. For example, the facial recognition technique may select one or more facial features of a face depicted in the image or the video frame, and compare the selected facial features to faces in a database. The database may include a mapping of the faces to identities, thereby permitting identification of the individual that is depicted in the image or the video frame.

SUMMARY

According to some implementations, a method may include selecting, by a device, an individual that is a candidate for authentication by facial recognition; identifying, by the device and based on selecting the individual, a facial area of the individual and an area of exposed skin of the individual, wherein the area of exposed skin of the individual is not associated with the facial area of the individual; obtaining, by the device, a first temperature associated with the facial area of the individual and a second temperature associated with the area of exposed skin of the individual; determining, by the device and based on the first temperature and the second temperature, whether an appearance of the facial area of the individual is likely altered by a face-altering technology, wherein the first temperature corresponding to the second temperature indicates that the appearance of the facial area of the individual is likely not altered by the face-altering technology, wherein the first temperature not corresponding to the second temperature indicates that the appearance of the facial area of the individual is likely altered by the face-altering technology; and selectively performing, by the device, facial recognition on the facial area of the individual based on whether the appearance of the facial area of the individual is likely altered by the face-altering technology.

According to some implementations, a device may include one or more memories and one or more processors, communicatively coupled to the one or more memories, to select an individual that is a candidate for authentication by facial recognition; obtain a temperature associated with a facial area of the individual; determine an estimated temperature for the facial area of the individual, wherein the estimated temperature is based on conditions of an environment associated with the individual; determine, based on the temperature and the estimated temperature, whether an appearance of the facial area of the individual is likely altered by a face-altering technology, wherein the temperature corresponding to the estimated temperature indicates that the appearance of the facial area of the individual is likely not altered by the face-altering technology, wherein the temperature not corresponding to the estimated temperature indicates that the appearance of the facial area of the individual is likely altered by the face-altering technology; and selectively perform facial recognition on the facial area of the individual based on whether the appearance of the facial area of the individual is likely altered by the face-altering technology.

According to some implementations, a non-transitory computer-readable medium may store one or more instructions that, when executed by one or more processors of, may cause the one or more processors to select an individual that is a candidate for authentication by facial recognition; identify, based on selecting the individual, a facial area of the individual and an area of exposed skin of the individual, wherein the area of exposed skin of the individual is not associated with the facial area of the individual; obtain a first temperature associated with the facial area of the individual and a second temperature associated with the area of exposed skin of the individual; determine an estimated temperature for the facial area of the individual, wherein the estimated temperature is based on conditions of an environment associated with the individual; determine, based on the first temperature, the second temperature, and the estimated temperature, whether an appearance of the facial area of the individual is likely altered by a face-altering technology, wherein the first temperature corresponding to the second temperature or the estimated temperature indicates that the appearance of the facial area of the individual is likely not altered by the face-altering technology, wherein the first temperature not corresponding to the second temperature and the estimated temperature indicates that the appearance of the facial area of the individual is likely altered by the face-altering technology; and selectively perform facial recognition on the facial area of the individual based on whether the appearance of the facial area of the individual is likely altered by the face-altering technology.

DETAILED DESCRIPTION

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

Facial recognition may be performed to authenticate an identity of an individual, determine an identity of an individual of interest (e.g., an individual suspected of committing a crime), identify an individual of interest (e.g., identify an individual from a crowd), and/or the like. In one example, a financial institution may perform facial recognition on an individual when the individual is attempting to access an account. In particular, the financial institution may perform the facial recognition in order to authenticate an identity of the individual before permitting the individual to access the account.

Sometimes, an individual may attempt to defeat facial recognition by altering an appearance of the individual's face. For example, the individual may wear a mask (e.g., a mask of another individual's face) or a facial prosthetic (e.g., a prosthetic nose) in an attempt to defeat facial recognition. Masks and facial prosthetics have reached a level of sophistication that makes detection of a mask or a facial prosthetic difficult and technically complex. As a result, a facial recognition system may misidentify, or fail to identify, the individual that is attempting to defeat facial recognition. Thus, the facial recognition system may waste resources (e.g., processor resources, memory resources, and/or the like) performing facial recognition on facial features of the individual that are falsified or intentionally obscured. In addition, misidentification of the individual may permit the individual to engage in illegal activity, such as fraudulently accessing a financial account that belongs to another individual. In such a case, a financial institution that maintains the financial account may consume resources (e.g., computing resources and/or network resources) involved in identifying, investigating, and/or correcting the illegal activity.

Some implementations described herein provide a detection platform that may detect an attempt to defeat facial recognition using a face-altering technology (e.g., a mask, a facial prosthetic, and/or the like). The detection platform may identify a facial area of an individual that is a candidate for authentication by facial recognition, and may identify a characteristic of the facial area. For example, the characteristic may be a temperature of the facial area, a level of perspiration of the facial area, a depth of an eye recess of the facial area, and/or the like. Based on the characteristic, the detection platform may determine whether an appearance of the facial area is likely altered, and may selectively perform facial recognition on the individual based on whether the appearance of the facial area is likely altered. For example, the detection platform may not perform facial recognition on the individual based on determining that the appearance of the facial area is likely altered.

In this way, the detection platform conserves computing resources involved in facial recognition that would otherwise be wasted if facial recognition was performed on individuals using a face-altering technology (e.g., because facial recognition is unlikely to accurately identify such individuals). Moreover, the detection platform can reduce instances of misidentification caused by face-altering technology (e.g., masks), thereby conserving computing resources involved in identifying, investigating, and/or correcting illegal activity that may otherwise be permitted by misidentification.

FIGS. 1A and 1B are diagrams of one or more example implementations 100 described herein. As shown in FIGS. 1A and 1B, example implementation(s) 100 may include a detection platform. The detection platform may be associated with an entity that performs facial recognition, such as a financial institution, a government agency (e.g., a police department, a transportation security agency, and/or the like), a school, a stadium, and/or the like. In some implementations, the detection platform may be associated with a financial institution that performs facial recognition in order to authenticate an individual to access a secure area. The secure area may be an account maintained by the financial institution that may be accessed via a transaction device, such as an automated teller machine (ATM) device.

The detection platform may be associated with one or more cameras and/or one or more sensors. The one or more cameras may be configured to capture an image or a video of an individual. The one or more sensors may be configured to detect and report one or more measurable parameters of the individual. For example, the one or more sensors may detect a temperature associated with the individual, a level of moisture associated with the individual, and/or the like. In some implementations, the detection platform may include the one or more cameras and/or the one or more sensors. Additionally, or alternatively, another device that is accessible to the detection platform may include the one or more cameras and/or the one or more sensors. For example, a transaction device (e.g., an ATM device) that is in communication with the detection platform may include the one or more cameras and/or the one or more sensors, and may provide data obtained by the one or more cameras and/or the one or more sensors to the detection platform.

The detection platform may implement a facial recognition system. The facial recognition system may utilize a facial recognition technique to identify a face of an individual. For example, the facial recognition technique may identify facial features (e.g., eyes, nose, mouth, jaw, cheekbones, and/or the like) of the individual from an image of the individual's face, and may determine a data set that represents a relative position, size, and/or shape of the facial features. The data set may be compared to other data sets representing facial features of known individuals in order to identify the individual. The data sets representing facial features of known individuals may be stored in a data structure (e.g., a data repository, a database, a table, a list, and/or the like) of the detection platform or accessible to the detection platform.

As shown in FIG. 1A, and by reference number 105, the detection platform may select an individual that is a candidate for authentication by facial recognition. In some cases, the individual may be utilizing a face-altering technology, such as a mask (e.g., a latex mask), a facial prosthetic, a bandage, an eye patch, and/or the like.

In some implementations, the detection platform (e.g., using a camera) may select the individual as the candidate for authentication by facial recognition if the individual enters a particular area (e.g., a bank, a stadium, an airport, and/or the like). For example, the detection platform may select the individual if the individual enters a particular area associated with a transaction device, such as a checkout area of a merchant, an ATM vestibule, and/or the like. In such a case, the particular area may include a proximity (e.g., 10 feet, 25 feet, 50 feet, and/or the like) of the transaction device. Thus, the detection platform may select the individual as the candidate for facial recognition if the individual is approaching the transaction device (e.g., enters the proximity). In some implementations, the detection platform may distinguish (e.g., utilizing a machine learning model) between individuals entering the proximity in order to use the transaction device and those merely passing through, based on a behavior of an individual, such as a direction of travel of the individual, a direction of an eye gaze of the individual, whether the individual is reaching into a bag or a pocket, and/or the like.

In some implementations, the detection platform may select the individual as the candidate for authentication by facial recognition if the individual requests access to a secure area. For example, the detection platform may select the individual if the individual requests access to an account (e.g., by inserting a transaction card into a transaction device, swiping a transaction card at a transaction device, and/or the like). As another example, the detection platform may select the individual if the individual requests access to a physical area (e.g., by entering an access code or presenting a credential at an access control system of the physical area).

As shown by reference number 110, the detection platform may identify a facial area of the individual selected as the candidate for facial recognition. For example, the detection platform may capture, or obtain, an image (e.g., a photograph or a video frame of a video) of the individual in order to identify the facial area of the individual from the image. In some implementations, a camera of a transaction device (e.g., an ATM device) may capture an image of the individual and provide the image to the detection platform. Additionally, or alternatively, a camera associated with a physical area (e.g., an ATM vestibule, an airport, a stadium, and/or the like) may capture an image of the individual and provide the image to the detection platform.

The detection platform may process the image of the individual to identify the facial area of the individual. For example, the detection platform may process the image using an artificial intelligence technique, such as machine learning, deep learning, and/or the like. For example, the detection platform may use a machine learning (e.g., computer vision) model to identify the facial area. For example, the detection platform may train the machine learning model based on one or more parameters associated with a facial area, such as shape, color, arrangement of features, and/or the like. The detection platform may train the machine learning model, according to the one or more parameters, using historical data associated with faces (e.g., images of faces). Using the historical data and the one or more parameters as inputs to the machine learning model, the detection platform may train the machine learning model to identify the facial area from an image of the individual. In some implementations, the detection platform may obtain and utilize a machine learning model that was trained by another device.

In some implementations, the detection platform may identify one or more other bodily areas of the individual from an image of the individual, in a manner similar to that described above. For example, the detection platform may identify an area of exposed skin of the individual that is not associated with the facial area of the individual. The area of exposed skin may relate to an ear, a neck, an arm, a hand, a leg, and/or the like of the individual.

As shown in FIG. 1B, and by reference number 115, the detection platform may identify a characteristic of the facial area of the individual. The characteristic may be unrelated to a facial feature (e.g., unrelated to eyes, a nose, a mouth, a jaw, and/or the like) of the facial area. For example, the characteristic may relate to a temperature of the facial area or a level of moisture (e.g., perspiration) of the facial area.

In some implementations, the detection platform may obtain the temperature of the facial area. In such a case, the detection platform may obtain the temperature of the facial area from a measurement of a temperature sensor. For example, the detection platform may obtain the temperature of the facial area from a measurement of an infrared (IR) sensor. In such a case, after identifying the facial area, the detection platform may cause the IR sensor to measure a level of IR light associated with the facial area. The detection platform may convert the measured level of IR light to a temperature. In some implementations, the IR sensor may be associated with an IR light source, and the IR sensor may measure a level of IR light from the IR light source that is reflected off the facial area.

In some implementations, the IR sensor and/or the IR light source may be stationary, and positioned so as to be directed to the facial area of the individual (e.g., positioned so as to be directed to the facial area of the individual when the individual is using an ATM device, entering an ATM vestibule, entering an airport, and/or the like). Alternatively, the IR sensor and/or the IR light source may be configured to change position to permit the IR sensor and/or the IR light source to be directed at the facial area of the individual during a movement of the individual.

In some implementations, the detection platform may include the IR sensor and/or the IR light source. Additionally, or alternatively, another device that is accessible to the detection platform may include the IR sensor and/or the IR light source. For example, a transaction device (e.g., an ATM device) that is in communication with the detection platform may include the IR sensor and/or the IR light source, and may provide IR light measurements obtained by the IR sensor to the detection platform.

In some implementations, the detection platform may obtain the level of moisture (e.g., perspiration) of the facial area. In such a case, the detection platform may obtain the level of moisture using a machine learning (e.g., computer vision) model in a manner similar to that described above. For example, the detection platform may train the machine learning model to identify perspiration from an image of the facial area of the individual. In some implementations, the detection platform may obtain and utilize a machine learning model that was trained by another device. The machine learning model may determine the level of moisture as a total area of the facial area where perspiration is identified, a percentage area of the facial area where perspiration is identified, and/or the like.

Additionally, or alternatively, the detection platform may obtain the level of moisture from an IR sensor, such as an IR sensor as described above. For example, the IR sensor may take IR light measurements, which may be converted to temperature measurements, from a plurality of locations on the facial area of the individual. Locations where perspiration is present may have lower temperatures than locations where perspiration is not present. Accordingly, the detection platform may identify a location as being associated with perspiration when the location has a temperature that does not satisfy a particular threshold (e.g., a threshold based on temperature measurements from the plurality of locations). In addition, the detection platform may determine the level of moisture as a total area of the facial area where perspiration is identified, a percentage area of the facial area where perspiration is identified, and/or the like.

Additionally, or alternatively, the detection platform may obtain the level of moisture from a galvanometer that measures a galvanic skin response (i.e., a change in electrical resistance of skin caused by perspiration). The detection platform may determine the level of moisture by converting a level of electrical resistance measured by the galvanometer. The detection platform, or another device accessible to the detection platform (e.g., an ATM device), may include a galvanometer in order to measure a galvanic skin response of the individual. In such a case, the detection platform, or the other device, may instruct the individual to place the individual's facial area in contact with the galvanometer in order to measure a galvanic skin response of the individual's facial area.

In some implementations, the detection platform also may identify a characteristic of the area of exposed skin of the individual (e.g., an area of exposed skin of an ear, a neck, a hand, and/or the like of the individual). For example, the detection platform may obtain a temperature or a level of moisture of the area of exposed skin in a manner similar to that described above.

In some implementations, the identified characteristic of the facial area of the individual may be a recess associated with an eye of the individual. The detection platform may obtain a measurement of the recess using a machine learning (e.g., computer vision) model, in a manner similar to that described above. For example, the detection platform may train the machine learning model to determine a recess of an eye from an image of the facial area of the individual. In some implementations, the detection platform may obtain and utilize a machine learning model that was trained by another device.

As shown by reference number 120, the detection platform may determine whether an appearance of the facial area of the individual is likely altered by a face-altering technology (e.g., a mask, a facial prosthetic, and/or the like). For example, the detection platform may determine, based on the identified characteristic of the facial area and/or the identified characteristic of the area of exposed skin, whether the appearance of the facial area is likely altered by a face-altering technology.

In some implementations, the detection platform may compare the identified characteristic of the facial area and the identified characteristic of the area of exposed skin in order to determine whether the appearance of the facial area is likely altered. For example, the detection platform may compare the temperature of the facial area and the temperature of the area of exposed skin. Since a face-altering technology may reduce heat that is emitted or reflected by the facial area relative to the area of exposed skin, the detection platform may determine that the appearance of the facial area is likely altered when the temperature of the facial area and the temperature of the area of exposed skin do not correspond (e.g., the temperature of the facial area is outside of a threshold range, such as ±1%, ±5%, and/or the like, of the temperature of the area of exposed skin). Conversely, the detection platform may determine that the appearance of the facial area is likely not altered when the temperature of the facial area and the temperature of the area of exposed skin correspond.

As another example, the detection platform may compare the level of moisture (e.g., perspiration) of the facial area and the level of moisture of the area of exposed skin. Since a face-altering technology may obstruct perspiration present on the facial area, the detection platform may determine that the appearance of the facial area is likely altered when the level of moisture of the facial area and the level of moisture of the area of exposed skin do not correspond (e.g., the level of moisture of the facial area is outside of a threshold range, such as ±1%, ±5%, and/or the like, of the level of moisture of the area of exposed skin). Conversely, the detection platform may determine that the appearance of the facial area is likely not altered when the level of moisture of the facial area and the level of moisture of the area of exposed skin correspond.

In some implementations, the detection platform may compare the identified characteristic of the facial area to an estimated value for the characteristic of the facial area. For example, the detection platform may compare the temperature of the facial area to an estimated temperature for the facial area. The detection platform may utilize a machine learning model to determine the estimated temperature, in a manner similar to that described above. For example, the detection platform may train the machine learning model based on one or more parameters associated with a facial temperature, such as an outdoors temperature, a location of an individual (e.g., indoors or outdoors (e.g., a transaction device, such as an ATM device, may be located indoors or outdoors)), an indoors temperature, an amount of exposed skin of an individual, and/or the like. The detection platform may train the machine learning model, according to the one or more parameters, using historical data associated with facial temperatures. Using the historical data and the one or more parameters as inputs to the machine learning model, the detection platform may train the machine learning model to determine an estimated facial temperature for the facial area of the individual. In some implementations, the detection platform may obtain and utilize a machine learning model that was trained by another device. Since a face-altering technology may reduce heat that is emitted or reflected by the facial area, the detection platform may determine that the appearance of the facial area is likely altered when the temperature of the facial area and the estimated temperature for the facial area do not correspond (e.g., the temperature of the facial area is outside of a threshold range, such as ±1%, ±5%, and/or the like, of the estimated temperature for the facial area). Conversely, the detection platform may determine that the appearance of the facial area is likely not altered when the temperature of the facial area and the estimated temperature for the facial area correspond.

As another example, the detection platform may compare the level of moisture of the facial area to an estimated level of moisture for the facial area. The detection platform may utilize a machine learning model to determine the estimated moisture level, in a manner similar to that described above. Since a face-altering technology may obstruct perspiration present on the facial area, the detection platform may determine that the appearance of the facial area is likely altered when the level of moisture of the facial area and the estimated level of moisture for the facial area do not correspond (e.g., the level of moisture of the facial area is outside of a threshold range, such as ±1%, ±5%, and/or the like, of the estimated level of moisture for the facial area). Conversely, the detection platform may determine that the appearance of the facial area is likely not altered when the level of moisture of the facial area and the estimated level of moisture for the facial area correspond.

In some implementations, the detection platform may determine whether the appearance of the facial area of the individual is likely altered by a face-altering technology based on the measurement of the recess of the eye of the individual. For example, the detection platform may determine whether the measurement of the recess exceeds a threshold value associated with a normal recess of an eye. The threshold value may be based on an aggregate (e.g., average) measurement determined from a plurality of individuals (e.g., a plurality of individuals having one or more facial features that are similar to those of the individual). Since a face-altering technology, such as a mask, may protrude from the individual's face, thereby causing a deeper eye recess, the detection platform may determine that the appearance of the facial area is likely altered when the measurement of the recess of the eye of the individual exceeds the threshold value. Conversely, the detection platform may determine that the appearance of the facial area is likely not altered when the measurement of the recess of the eye of the individual does not exceed the threshold value.

In some implementations, the detection platform may employ any combination of the foregoing techniques for determining whether the appearance of the facial area of the individual is likely altered by a face-altering technology. For example, the detection platform may determine whether the appearance of the facial area is likely altered based on any one or more of whether a temperature of the facial area corresponds to a temperature of the area of exposed skin, whether a level of moisture of the facial area corresponds to a level of moisture of the area of exposed skin, whether a temperature of the facial area corresponds to an estimated temperature for the facial area, whether a level of moisture of the facial area corresponds to an estimated level of moisture for the facial area, or whether a recess of an eye of the individual exceeds a threshold value.

In some implementations, the detection platform may determine whether the appearance of the facial area of the individual is likely altered by a face-altering technology prior to performing facial recognition on the individual. For example, the detection platform may determine whether the appearance of the facial area is likely altered before the individual requests access to a secure area, to thereby determine whether facial recognition is to be performed on the individual. For example, the detection platform may determine whether the appearance of the facial area is likely altered when the individual is approaching a transaction device (e.g., before the individual requests access to a secure area via the transaction device). In this way, the detection platform may determine a manner in which the individual is to be authenticated before the individual requests access to a secure area, thereby improving a speed and an efficiency of an authentication process.

As shown by reference number 125, the detection platform may selectively perform facial recognition on the facial area of the individual based on whether the appearance of the facial area is likely altered by a face-altering technology. For example, the detection platform may determine not to perform facial recognition on the facial area based on determining that the appearance of the facial area is likely altered. In such a case, the detection platform may determine that the individual is to be authenticated according to a technique that does not include facial recognition. For example, the detection platform may prompt, or cause another device to prompt, the individual to provide a password, a personal identification number (PIN), a biometric identifier, and/or the like based on determining that the appearance of the facial area is likely altered. In this way, the detection platform conserves computing resources associated with facial recognition by determining not to perform facial recognition when facial recognition is unlikely to produce an accurate result (e.g., when the individual is utilizing a face-altering technology).

In some implementations, based on determining that the appearance of the facial area is likely altered, the detection platform may administer, or cause another device to administer, a facial expression challenge to the individual. For example, the detection platform, or the other device, may request that the individual perform one or more facial expressions, such as smiling, frowning, pouting, raising one or both eyebrows, and/or the like. Continuing with the previous example, the detection platform, or the other device, may determine whether the performed facial expressions indicate that the appearance of the facial area of the individual is likely altered by a face-altering technology. This may include determining (e.g., using a machine learning model) whether a relative position, size, shape, and/or the like of the performed facial expressions correspond to reference facial expressions (e.g., facial expressions performed by one or more individuals not utilizing a face-altering technology). Based on determining that one or more of the performed facial expressions do not correspond to the reference facial expressions, the detection platform, or the other device, may determine that the individual is not to be authenticated according to facial recognition.

In some implementations, the detection platform may perform one or more actions based on determining that the appearance of the facial area of the individual is likely altered by a face-altering technology. For example, if the individual is attempting to access a secure area (e.g., an account), the detection platform may lock the secure area (e.g., for a time period), require one or more additional authentication factors to access the secure area (e.g., for a time period), transmit a notification to a user device of an owner of the secure area indicating suspicious activity, transmit a notification to a user device of a law enforcement agency indicating suspicious activity, and/or the like. As another example, the detection platform may perform facial recognition on the facial area of the individual in order to determine an identity of a person being impersonated by the individual, and may lock one or more accounts associated with the person, require one or more additional authentication factors to access the one or more accounts, transmit a notification to a user device of the person indicating an impersonation attempt, transmit a notification to a user device of a law enforcement agency indicating an impersonation attempt, and/or the like.

In some implementations, the detection platform may determine to authenticate the individual according to facial recognition based on determining that the appearance of the facial area of the individual is likely not altered by a face-altering technology. In such a case, the detection platform may utilize a facial recognition system, as described above, to determine an identity of the individual based on an image of the individual. In some implementations, the detection platform may determine whether the identity matches that of an owner of an account the individual was attempting to access, an owner of a credential that the individual was using, and/or the like to thereby authenticate the individual. In this way, the detection platform performs facial recognition when facial recognition is likely to produce an accurate result (e.g., when the individual is not utilizing a face-altering technology), thereby conserving computing resources and reducing instances of misidentification as well as illegal activity that may be permitted by misidentification.

As indicated above, FIGS. 1A and 1B are provided as one or more examples. Other examples may differ from what is described with regard to FIGS. 1A and 1B.

A POS device may include an electronic device used to process transaction card payments at a retail location. The POS device may read information from a transaction card (e.g., a credit card, a debit card, a gift card, and/or the like), and may determine whether there are sufficient funds in an account associated with the transaction card for a transaction. The POS device may cause a transfer of funds from the account associated with the transaction card to an account of a retailer and may record the transaction.

Notably, while implementations described herein may describe detection platform 240 as being hosted in cloud computing environment 250, in some implementations, detection platform 240 may be non-cloud-based or may be partially cloud-based. For example, in some implementations, detection platform 240 may be implemented by transaction device 210.

Cloud computing environment 250 includes an environment that delivers computing as a service, whereby shared resources, services, and/or the like may be provided to transaction device 210, camera 220, sensor 230, and/or the like. Cloud computing environment 250 may provide computation, software, data access, storage, and/or other services that do not require end-user knowledge of a physical location and configuration of a system and/or a device that delivers the services. As shown, cloud computing environment 250 may include detection platform 240 and computing resource 245.

Computing resource 245 includes one or more personal computers, workstation computers, server devices, or another type of computation and/or communication device. In some implementations, computing resource 245 may host detection platform 240. The cloud resources may include compute instances executing in computing resource 245, storage devices provided in computing resource 245, data transfer devices provided by computing resource 245, and/or the like. In some implementations, computing resource 245 may communicate with other computing resources 245 via wired connections, wireless connections, or a combination of wired and wireless connections.

As further shown in FIG. 2, computing resource 245 may include a group of cloud resources, such as one or more applications (“APPs”) 245-1, one or more virtual machines (“VMs”) 245-2, virtualized storage (“VSs”) 245-3, one or more hypervisors (“HYPs”) 245-4, or the like.

Application 245-1 includes one or more software applications that may be provided to or accessed by transaction device 210, camera 220, sensor 230, and/or the like. Application 245-1 may eliminate a need to install and execute the software applications on transaction device 210, camera 220, sensor 230, and/or the like. For example, application 245-1 may include software associated with detection platform 240 and/or any other software capable of being provided via cloud computing environment 250. In some implementations, one application 245-1 may send/receive information to/from one or more other applications 245-1, via virtual machine 245-2.

Virtual machine 245-2 includes a software implementation of a machine (e.g., a computer) that executes programs like a physical machine. Virtual machine 245-2 may be either a system virtual machine or a process virtual machine, depending upon use and degree of correspondence to any real machine by virtual machine 245-2. A system virtual machine may provide a complete system platform that supports execution of a complete operating system (“OS”). A process virtual machine may execute a single program and may support a single process. In some implementations, virtual machine 245-2 may execute on behalf of a user, and may manage infrastructure of cloud computing environment 250, such as data management, synchronization, or long-duration data transfers.

Virtualized storage 245-3 includes one or more storage systems and/or one or more devices that use virtualization techniques within the storage systems or devices of computing resource 245. In some implementations, within the context of a storage system, types of virtualizations may include block virtualization and file virtualization. Block virtualization may refer to abstraction (or separation) of logical storage from physical storage so that the storage system may be accessed without regard to physical storage or heterogeneous structure. The separation may permit administrators of the storage system flexibility in how the administrators manage storage for end users. File virtualization may eliminate dependencies between data accessed at a file level and a location where files are physically stored. This may enable optimization of storage use, server consolidation, and/or performance of non-disruptive file migrations.

Hypervisor 245-4 provides hardware virtualization techniques that allow multiple operating systems (e.g., “guest operating systems”) to execute concurrently on a host computer, such as computing resource 245. Hypervisor 245-4 may present a virtual operating platform to the guest operating systems and may manage the execution of the guest operating systems. Multiple instances of a variety of operating systems may share virtualized hardware resources.

Network 260 includes one or more wired and/or wireless networks. For example, network 260 may include a cellular network (e.g., a long-term evolution (LTE) network, a code division multiple access (CDMA) network, a 3G network, a 4G network, a 5G network, another type of next generation network, and/or the like), a public land mobile network (PLMN), a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a telephone network (e.g., the Public Switched Telephone Network (PSTN)), a private network, an ad hoc network, an intranet, the Internet, a fiber optic-based network, a cloud computing network, or the like, and/or a combination of these or other types of networks.

In practice, there may be additional devices and/or networks, fewer devices and/or networks, different devices and/or networks, or differently arranged devices and/or networks than those shown in FIG. 2. Furthermore, two or more devices shown in FIG. 2 may be implemented within a single device, or a single device shown in FIG. 2 may be implemented as multiple, distributed devices. Additionally, or alternatively, a set of devices (e.g., one or more devices) of environment 200 may perform one or more functions described as being performed by another set of devices of environment 200.

For example, communication interface 370 may include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, a Wi-Fi interface, a cellular network interface, and/or the like.

Device 300 may perform one or more processes described herein. Device 300 may perform these processes based on processor 320 executing software instructions stored by a non-transitory computer-readable medium, such as memory 330 and/or storage component 340. As used herein, the term “computer-readable medium” refers to a non-transitory memory device.

For example, the detection platform (e.g., using computing resource 245, processor 320, memory 330, storage component 340, and/or the like) may determine, based on the first temperature and the second temperature, whether an appearance of the facial area of the individual is likely altered by a face-altering technology, as described above. In some implementations, the first temperature corresponding to the second temperature indicates that the appearance of the facial area of the individual is likely not altered by the face-altering technology. In some implementations, the first temperature not corresponding to the second temperature indicates that the appearance of the facial area of the individual is likely altered by the face-altering technology.
